CORSET-CLASP.

SPECIFICATION forming part of Letters Patent No. 249,923, dated November22, 1881,

Application filed April 11, 1881. (Model) To all whom it may concern.-

Be it known that I, WILLIAM F. GILBERT, of Derby, in the county of NewHaven and State of Connecticut, have invented a new Improvement inCorset-Clasps and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, Ill- Figure l, a top View; Fig. 2, a longitudinal centralsection enlarged Fig. 3, a transverse section Figs. 4 and 5, sections toillustrate the operation.

This invention relates to an improvement in the eye or loop attached toone of the steels of a corset for the purpose of engaging it with theheaded studs on the other steel, the object being to facilitate theengagement of one part with the other, and at the same time-preventaccidental disengagement and the invention consists in the constructionof the eye with a concave'recess upon its under side around the enlargedpart of the opening in the slot, so as to form a guide to the said slot,and also forming a raised stop on the upper surface, to be in rear ofthe head of the stud or hook when the parts are engaged, all as m orefull y hereinafter described.

A is the eye or loop, which may he of the usual outline or shape, andprovided with rivetholes a, or other devices for attachment to the steel0. b is the slot, having its rear end enlarged, as at d, for the head ofthe stud or hook to pass through. This pieceAis cut from sheet metal inthe usual manner, and in its under sidea concave cavity,B,is formedaround the enlarged part of the slot (1, as seen in Figs. 2 and 3. Thedepression to form the cavityB produces a corresponding convex raisedportion around the said opening (I, as shown on the outside. The loop isattached to one of the steels, C, as seen in Fig. 4, the other steel. D,titted with a headed stud, E, alsoin the usual manner.

In placing the two parts together, as for clasping, the whole diameterof the cavity B is presented to the head of the stud, so thatit isreadily entered, and when so entered the sides of the cavity serve as aguide to direct the head to the opening d, through which it passes, asseen in Fig. 4.. It then moves into the slot 1), as seen in Fig. 5. Thedepth of the depression or recess B is just sufficient to permit thehead to pass freely through. Then, when it has been drawn into the slot1), the end of the loop naturally moves and stands toward the head, asseenin Fig. 5. In this condition the raised part prevents the head frompassing back so as to escape through the enlarged part d of the slot,unless forced so to do by the wearer. Hence the usual liability todetachment is avoided.

I dovnot wish to be understood as broadly claiming a loop forcorset-clasps having a stop combined therewith to prevent accidentaldisengagement i'rom its hook or stud, as such, I am aware, is not new.

I claim- The herein-described improvement in corsetclasps, consisting ofthe loop constructed with a concave recess upon the under side aroundthe enlarged partof the slot made to receive the headed stud or hook,substantially as described.
